An object of this invention isy to provide a simplified attachment for a water closet which controls the quantity of water used during a single flushing operation, said attachment being arranged to control the extent of travel of the valve in the water closet.

Ancillary objects and features of importance will becomev apparent in following the description of the illustrated form of the invention.

In the drawings: v

Figure 1 is a fragmentary sectional view of a typical water closet having the attachment disposed therein and showing in phantom the location and position of some of the elements when only a portion of the full amount of liquid in the water closet is used for a single cycle of 0peration;

Figure 2 is a fragmentary sectional view of the water closet illustrating the relative position of various elements when the water closet mechanism is used to empty the water substantially entirely therefrom, as in normal and unimpeded operation; and

Figure 3 is an enlarged sectional view taken substantially on the line 3-3 of Figure 1 and inl the direction of the arrows.

There is a standard Water closet tank I0 illustrated, this water closet having a standard float controlled inlet valve I2 fed by the riser pipe i4. The valve has a discharge pipe I6 connected to it which opens into the tank I0.

A float or ball 26 is connected to a oat beam 22 which is operatively connected with the valve I2 for operation thereof in response to the fluid level in the tank I0.

A standard resiliently buoyant valve 2'4`is re` movably disposed on the seat 26, this seat havingk 34, the cam contacting the lever 36 to operatev An 'arm 38 is connected to the the Valve 24. double cam 32 and has a flexible element, asthe chain 39, connected to it, the arm 38 and the chain forming a part of the attachment.

Included in the standard equipment of the water closet mechanism is the support 40 which is carried by the overow pipe 30 and which mounts the lever 36 intermediate its ends for pivotal movement. The link 42, pivoted at one end to the lever 36, is arranged to lift the valve stem 44, this valve stem being fixed to the valve 24.

The usual and standard operation of the water closet mechanism is deemed known to those skilled y in the art. The attachment including the arm 38, chain 39 and arm 46 is so arranged as to cause a full flush or a partial flush, depending upon which way the double cam 32 is operated. When the handle (unshown) attached to the spindle 34 is rotated in a direction so as to cause operation as disclosed in Figure 2, the chain 39 is pulled tight, thereby pulling the upper end of the arm 46. This ycauses the arm 46 to be pivoted about the pivot pin 48 as an axis, swinging the lower end of the arm 46 away from the valve 24. Since the valve is lifted by the lever 36 and the arm 46 is swung as disclosed in phantom in Figure 2, the valve 24 is raised the full amount. Hence, the

water closet operation is such as though the attachment were not present.

However, when the unshown handle is rotated in the opposite direction (Figure 1), the chain 39 is slackened. Due to the weight of the chain and gravity, the arm 46 pivots about the pin 48 as an axis so that the hook 50 at the end of the arm 46 contacts the top surface of the valve 24. 'I'his hook is made of two sections of the wire forming the arm 46, said sections being bent at substantially right angles to each other. Then, when the oat beam 22 is lowered, the arm 46 is correspondingly lowered. Since this arm is now disposed on the top surface of the valve 24, it pushes the valve Ldown with it. Hence, after the valve rests upon the seat in this manner, no more Water escapes from the tank I9. Once the valve has been seated in this manner, water having started to flow thru thevalve l2 begins tocompletely fill the tank l0 Ato capacity. As the tank I3 fills, the

beam 22 is lifted, carrying with it the arm 46, inasmuch as this arm is connected to the beam by c means of the pivot pin 48 which passes through a platev54, welded or otherwise rigidly fixed to the arm46 and also which is connected to the bearing 56 held in place on the beam 22 by means of the set screw 58.

Having described the invention, what is claimed asnew is :r y

In a flushing device comprising a tank having an outlet, a buoyant valve for closing the outlet, an inlet valve and float means for actuating said inlet valve, a water saver including a spindle journaled in the tank, a lever pivotally mounted in the tank, a link operatively connecting one end 3 of the lever with the buoyant valve for opening same, a double cam on the spindle operatively engaged with the other end portion of the lever for actuating same for opening the buoyant valve when said spindle is rotated in either direction, an 5 arm xed on the spindle, an arm pivotally mounted on the float means and engageable with the buoyant valve for prematurely closing same for a partial flush when said float means drops with the level of the liquid in the tank, and a. flexible member operatively connecting the 'firstnamed arm to the second-named arm for swinging the latter to inoperative position away from 4. the buoyant valve when the spindle is rotated in one direction for a full flush.
